C
void WF_GetMultiCastFilter( UINT8 multicastFilterId, UINT8 multicastAddress[6] );
Description
Gets the current state of the specified Multicast Filter.
Normally would call SendGetParamMsg, but this GetParam returns all 6 address filters + 2 more bytes for a total of 48 bytes plus header. So, doing this msg manually to not require a large stack allocation to hold all the data.
Exact format of returned message is:
|
[0] -- always mgmt response (2) |
|
[1] -- always WF_GET_PARAM_SUBTYPE (16) |
|
[2] -- result (1 if successful) |
|
[3] -- mac state (not used) |
|
[4] -- data length (length of response data starting at index 6) |
|
[5] -- not used |
|
[6-11] -- Compare Address 0 address |
|
[12] -- Compare Address 0 group |
|
[13] -- Compare Address 0 type |
|
[14-19] -- Compare Address 1 address |
|
[20] -- Compare Address 1 group |
|
[21] -- Compare Address 1 type |
|
[22-27] -- Compare Address 2 address |
|
[28] -- Compare Address 2 group |
|
[29] -- Compare Address 2 type |
|
[30-35] -- Compare Address 3 address |
|
[36] -- Compare Address 3 group |
|
[37] -- Compare Address 3 type |
|
[38-43] -- Compare Address 4 address |
|
[44] -- Compare Address 4 group |
|
[45] -- Compare Address 4 type |
|
[46-51] -- Compare Address 5 address |
